TECHNICAL FIELD

The present disclosure relates to the technical field ofair-conditioning devices, and more particularly relates to an aromadiffuser and an oil supply method.

BACKGROUND

An aroma diffuser is an aromatherapy device. It typically atomizes watermixed with an essential oil by using high-frequency oscillation such asultrasonic vibration and then diffusing it into the air to make the airfull of fragrance.

The aroma diffuser typically supplies the essential oil by oil dripping.That is, the essential oil is dripped into the water all at once.Because it has a density lower than that of water, the essential oilwould float on the water surface after being dripped into a tank of thearoma diffuser. As such, when the aroma diffuser is operating, theessential oil concentration in the tank would decrease as the time ofoperation progresses, because the essential oil and water are atomizedand diffused simultaneously. Therefore, the fragrance of the atomizedvapor would become increasingly light, resulting in an unsatisfactoryuser experience.

Embodiment 1

As shown in FIGS. 1 to 5, the present application provides an aromadiffuser which is configured to release an atomized liquid such as watermixed with the essential oil into the air. The aroma diffuser mayinclude a main body 1 and an oil storage tube 5 which is configured tostore an essential oil 4. For example, as shown in FIGS. 2 and 3, aliquid storage chamber 11 may be disposed within the main body 1, andthe liquid storage chamber 11 may be configured to store a liquid 3. Theliquid 3 may be a liquid such as pure water or water mixed with theessential oil, or may be other liquids, which is not limited herein. Ingeneral, when the aroma diffuser is assembled and capable of working,the oil storage tube 5 may be disposed within the liquid storage chamber11 to enable the entire aroma diffuser to be compact. However, the oilstorage tube 5 may be separated from the main body 1, or may beintegrally disposed in the main body 1. In this embodiment, the oilstorage tube 5 may be independent of the main body 1 and have a tubularstructure as shown in FIG. 1. During the assembly, the oil storage tube5 may be fixed within the main body. The oil storage tube 5 may storethe essential oil 4 via a cavity 2, and the bottom portion of the oilstorage tube 5 may be in fluidic communication with the liquid storagechamber 11, ensuring that the essential oil 4 flows from the oil storagetube 5 into the liquid storage chamber 11.

The main body 1 may be further provided with an atomization apparatus(not shown) such as an ultrasonic atomizing sheet or the like. Theliquid 3 in the liquid storage chamber 11 or the liquid 3 in a watertank in fluidic communication with the liquid storage chamber 11 may beatomized by the atomization apparatus, and the mist produced may be thendischarged outward through an air outlet pipe (not shown).

During the use of the aroma diffuser, it is necessary to add the liquid3 such as water into the liquid storage chamber 11 and the essential oil4 into the oil storage tube 5 in advance. The liquid level of theessential oil 4 in the oil storage tube 5 may need to be higher than theliquid level of the liquid 3 in the liquid storage chamber 11, so thatthe essential oil in the oil storage tube 5 may flow from the bottom ofthe oil storage tube 5 into the liquid storage chamber 11 as the liquid3 in the liquid storage chamber 11 is consumed.

Referring to FIG. 4, since the liquid level of the essential oil 4 inthe oil storage tube 5 is higher than the liquid level of the liquid 3in the liquid storage chamber 11 after the liquid 3 is added into theliquid storage chamber 11 and the essential oil 4 is added into the oilstorage tube 5, and due to the poor compatibility between the essentialoil 4 and the liquid 3 (in this embodiment, the liquid 3 is mainlywater), the essential oil 4 does not rapidly dissolve into the liquid 3but is still stored in the oil storage tube 5. A used herein, the poorcompatibility between the essential oil 4 and the liquid 3 may referthat a solubility of the essential oil 4 in the liquid 3 is smaller thana threshold, such as smaller than 0 g/100 g, or smaller than 0.01 g/100g, or smaller than 1 g/100 g, etc.

The bottom portion of the oil storage tube 5 may be in fluidiccommunication with the liquid storage chamber 11, and the area where theessential oil 4 and the liquid 3 contact at the bottom portion of theoil storage tube 5 may be regarded as the bottom surface of theessential oil 4. The distance from the bottom surface of the essentialoil 4 to the surface (referring to the top surface where the essentialoil 4 contacts with the air) of the essential oil 4 is h1, and thedistance from the bottom surface of the essential oil 4 to the surface(referring to the top surface where the liquid 3 contacts with the air)of the liquid 3 is h2. From the analysis based on relevant knowledge inphysics, the following conclusions can be obtained.

The air above the liquid 3 is in fluidic communication with the airabove the essential oil 4. Since the pressure of the air to the surfaceof the essential oil 4 is atmospheric pressure p1 and the pressure ofthe air to the surface of the liquid 3 is also atmospheric pressure p1,which means the air exerts the same pressure to the surface of theliquid 3 as to the surface of the essential oil 4, the pressure of theair to both the essential oil 4 and the liquid 3 is the same and theeffect of the pressure of the air is canceled. For the pressure betweenthe liquid 3 and the bottom surface of the essential oil 4, at thebottom surface of the essential oil 4, the pressure of the liquid 3 tothe essential oil 4 is p2=ρ1gh2, and the pressure of the essential oil 4to the liquid 3 is p3=ρ2gh1, where p1 is the density of the liquid 3,and ρ2 is the density of the essential oil 4. When p2=p3, that is, whenρ1gh2=ρ2gh1, the height of the essential oil 4 is kept stable. Most ofthe liquid 3 is water, the density of the essential oil 4 is smallerthan that of the liquid 3, that is, ρ1>ρ2, and correspondingly h2<h1.Therefore, the height of the essential oil 4 can be higher than theheight of the liquid 3, and the height difference Δh between themdepends on the density of the liquid 3 and the density of the essentialoil 4.

From the above analysis, the continuous atomization and consumption ofthe liquid 3 cause the continuous decrease of h2, and p2 decreasesaccordingly, resulting in p2<p3, which means the pressure exerted to theessential oil 4 by the liquid 3 is lower than the pressure exerted tothe liquid 3 by the essential oil 4, or in other words the pressureexerted to the liquid 3 by the essential oil 4 is higher than thepressure exerted to the essential oil 4 by the liquid 3, such that theessential oil 4 will flow into the liquid storage chamber 11 until thebalance between the liquid 3 and the essential oil 4 is achieved again.Since

${{\Delta\; h} = {{h_{1} - h_{2}} = {\left( {\frac{\rho\; 1}{\rho\; 2} - 1} \right)h_{2}}}},$Δh also decreases as h2 decreases, that is, the height differencebetween the liquid 3 and the essential oil 4 becomes increasinglysmaller. In the actual test, the height of the liquid 3 and the heightof the essential oil 4 (both with the bottom surface of the liquidstorage chamber 11 as the height origin) vary with the atomization time.As shown in FIG. 5. S1 is the curve of the height of the essential oil 4changing with the atomization time, and S2 is the curve of the height ofthe liquid 3 changing with the atomization time.

When the aroma diffuser works normally, the bottom portion of the oilstorage tube 5 may be in fluidic communication with the liquid storagechamber 11. The liquid 3 such as water may be added into the liquidstorage chamber 11 and the essential oil 4 may be added into the oilstorage tube 5. The liquid level of the essential oil 4 may need to behigher than the liquid level of the liquid 3. Due to the poorcompatibility between the essential oil 4 and the liquid 3 and thehigher density of the liquid 3, the essential oil 4 can be kept in theoil storage tube 5. As the aroma diffuser continues to work, the liquid3 in the liquid storage chamber 11 may be continuously atomized, theliquid level of the liquid 3 continuously may descend, and the liquidlevel of the essential oil 4 may also continuously descend. Theessential oil 4 at the bottom portion may flow into the liquid storagechamber 11 and mixes with the liquid 3, thereby implementing thecontinuous oil supply to the liquid 3 in the liquid storage chamber 11.

In view of the above, when the aroma diffuser is working normally, theair above the liquid 3 may be in fluidic communication with the airabove the essential oil 4, and the pressure of the air to the surface ofthe liquid 3 is the same as the pressure of the air to the surface ofthe essential oil 4. As the liquid 3 in the liquid storage chamber 11 isbeing consumed, at the bottom surface of the essential oil 4, thepressure of the essential oil 4 to the liquid 3 would become strongerthan the pressure of the liquid 3 to the essential oil 4, so that theessential oil 4 would flow into the liquid storage chamber 11. Ofcourse, if the essential oil 4 does not yet reach the bottom surface ofthe oil storage tube 5, the pressure of the essential oil 4 to theliquid 3 would push the bottom surface of the essential oil 4 to movedownward to the bottom end of the oil storage tube 5.

Compared with the way that the essential oil is directly dripped intothe water in the related art, the aroma diffuser in this embodiment cancontinuously and stably supply the oil to the liquid 3 in the liquidstorage chamber 11. During the use of the aroma diffuser, theconcentration of the essential oil 4 may be kept stable, thereby keepingthe essential oil concentration in the atomized vapor stable, andavoiding the decrease of the essential oil concentration with theincrease of the use time.

In this embodiment, for the convenience of the user, the oil storagetube 5 may be a separate component. The bottom portion of the cavity 2of the oil storage tube 5 may be provided with a first sealing member 61for sealing the cavity 2, and the top portion of cavity 2 may beprovided with a second sealing member 62 for sealing the cavity 2. Theoil storage tube 5 may be made of a plastic, an aluminum, a glass orother materials as long as it is not corroded by the essential oil 4. Inaddition, the oil storage tube 5 may have better be made of a dark oropaque material to avoid the influence of the light on the essential oil4 in it. The first sealing member 61 and the second sealing member 62may be made of aluminum films, plastic films or other materials as longas two ends of the oil storage tube 5 are respectively sealed. Since twoends of the cavity 2 of the oil storage tube 5 need to be sealed, theessential oil 4 may be added into the cavity 2 in advance before twoends of the cavity 2 are sealed. During the use, the user can directlycarry or store the oil storage tube 5, and the used oil storage tube 5in the main body 1 can be replaced with another new oil storage tube 5,thereby greatly improving the portability of the essential oil andoffering the convenient to the user.

In order to fix the oil storage tube 5 on the main body 1, a fixingbracket 7 may be disposed within the main body 1, which fixes the oilstorage tube 5. The fixing bracket 7 may be a clamping mechanism, suchas a clip to clamp the oil storage tube 5. The fixing bracket 7 may alsobe configured as a structure with a holding hole which can hold the oilstorage tube 5, and the holding hole can be tightly joined to the oilstorage tube 5. The fixing bracket 7 can be fixed to the main body 1 bymeans of sticking, or fixing via a fastener.

Because both ends of the cavity 2 of the oil storage tube 5 need to besealed when the oil storage tube 5 is used to store the essential oil,and both ends of the cavity 2 need to be opened when the aroma diffusingapparatus is working thus enabling the upper (or top) end of the cavity2 to be in fluidic communication with the air inside the liquid storagechamber, so that the essential oil 4 in the cavity 2 may flow into theliquid storage chamber 11. In order to puncture the first sealing member61 at the bottom portion of the cavity 2, a first puncture member 71 maybe disposed on the fixing bracket 7. The first puncture member 71 may bea needle with a sharp end. The first puncture member 71 may be disposedat the bottom portion of the oil storage tube 5. When the oil storagetube 5 is fixed on the fixing bracket 7, the first sealing member 61 canbe punctured by the first puncture member 71 to be in fluidiccommunication with the cavity 2 with the liquid storage chamber 11. Inorder to puncture the second sealing member 62 at the top portion of thecavity 2, the main body 1 may be provided with a top cover 8 above thefixing bracket 7, and the bottom of the top cover 8 may be provided witha second puncture member 81. When the oil storage tube 5 is installed onthe fixing bracket 7 and the top cover 8 is installed on the main body1, the second sealing member 62 can be punctured by the second puncturemember 81 enabling the top of the cavity 2 to be in fluidiccommunication with the air inside the liquid storage chamber 11. Whenthe apparatus works, both ends of the oil storage tube 5 can be easilypunctured through the cooperation of the first puncture member and thesecond puncture member 72.

In this embodiment, the top cover 8 may be a press-type top cover. Thesecond puncture member 81 may move downward when the top cover 8 ispressed and return upward when the top cover 8 is not pressed. After thetop cover 8 is installed on the main body 1, the second puncture member81 may not contact with the second sealing member 62. When the top cover8 is pressed downward externally, the second puncture member 81 may movedownward to the second sealing member 81 and punctures the secondsealing member 62. After that, the second puncture member 81 may moveupward and disengage from the oil storage tube 5 to avoid blocking anupper puncture hole formed by the second puncture member 81 puncturingthe second sealing member 81.

In order to make the first puncture member 71 easily puncture the firstsealing member 61, in this embodiment, an abutment portion 82 may bedisposed on the top of the top cover 8. When the top cover 8 is presseddownward, the abutment portion 82 may descend and abut the oil storagetube 5 to drive the oil storage tube 5 to move downward to the firstsealing member 61, so that the first sealing member 61 may be puncturedby the first puncture member 71.

In order to prevent the first puncture member 71 from blocking thepuncture hole to affect the flow of the essential oil after the firstsealing member 61 is punctured by the first puncture member 71, thefirst puncture member 71 may include a puncture head and a main partconnected to the puncture head. The top of the puncture head may bepointed. The maximum width of a cross section of the puncture head maybe greater than that of a cross section of the main part. When the firstpuncture member 71 punctures the first sealing member 61 by using itstop, a puncture hole having a larger cross section may be formed. Sincethe bottom of the first puncture member 71 is narrower, a gap may existbetween the periphery of the first puncture member 71 and the puncturehole. The cavity 2 may be in fluidic communication with the liquidstorage chamber 11 via the periphery of the first puncture member 71.Similarly, the structure of the second puncture member 81 may be similarto that of the first puncture member 71.

Besides the above-mentioned structure configured on the first puncturemember 71, a rebound device such as a compression spring may be disposedon the fixing bracket 7 or at the bottom portion of the oil storage tube5. In an embodiment, the top of the rebound device may carry the oilstorage tube 5. When the oil storage tube 5 is pressed downward and therebound device is compressed, the first sealing member 61 may bepunctured by the first puncture member 71. When the pressed oil storagetube 5 is released, the rebound device may drive the oil storage tube 5to move upward by a certain distance, so that the oil storage tube 5disengages from the first puncture member 71 to prevent the firstpuncture member 71 from blocking the puncture hole.

For the aroma diffuser with the oil storage tube 5 of which both endsare sealed, after the essential oil is added in the oil storage tube 5in advanced and the oil storage tube 5 is sealed, the following stepscan be used for supplying the essential oil:

a. adding water into the liquid storage chamber 11;

b. fixing the oil storage tube 5 containing the essential oil 4 on thefixing bracket 7, disposing the top cover 8 on the main body 1, lettingthe first puncture member 71 puncture the first sealing member 61, andletting the second puncture member 81 puncture the second sealing member62.

The water level of the water in the liquid storage chamber 11 may bebetween the bottom of the oil storage tube 5 and a preset highest oillevel of the oil storage tube 5.

Through the above-mentioned method, after the first sealing member 61 ispunctured by the first puncture member 71 and the second sealing member62 is punctured by the second puncture member 81, the top portion of theoil storage tube 5 may be in fluidic communication with the liquidstorage chamber 11 while the bottom portion of the oil storage tube 5may be in fluidic communication with the liquid 3 inside the liquidstorage chamber 3, so that the oil storage tube 5 can continuouslysupply oil to the liquid 3 in the liquid storage chamber 11 as the aromadiffuser works.

In this embodiment, the highest water level of the liquid storagechamber 11 refers to the highest area of the water in the liquid storagechamber 11. The highest water level may be preset in a certain positionof the liquid storage chamber 11 and the position may be marked toprompt the user (for example, mark the position of max2 in FIG. 4). Thehighest water level may be a default value, for example, the highestwater level may be located at a water inlet on the top of the liquidstorage chamber 11. The lowest water level of the liquid storage chamber11 may be generally at the bottom of the liquid storage chamber 11. Thehighest oil level refers to the highest area of the essential oil 4 inthe oil storage tube 5. The highest oil level may be preset in a certainposition of the oil storage tube 5 and the position may be marked toprompt the user (for example, mark the position of max1 in FIG. 4). Thehighest oil level may be a default position, for example, the highestoil level may be located at the top end of the oil storage tube 5. Thelowest oil level may be generally at the bottom of the oil storage tube5. If the highest water level of the liquid storage chamber 11 is lowerthan the bottom of the oil storage tube 5, the essential oil 4 in theoil storage tube 5 will completely flow into the water surface of theliquid 3 in the liquid storage chamber 11, and the essential oil 4cannot be stored, so that the continuous oil supply cannot beimplemented. Therefore, the highest water level of the liquid storagechamber 11 may need to be higher than the bottom of the oil storage tube5. The highest water level of the liquid storage chamber 11 may alsoneed to be lower than the highest oil level of the oil storage tube 5,thereby ensuring that the oil storage tube 5 has oil storage space forstoring the essential oil 4 and that the essential oil 4 does notoverflow from the top portion of the oil storage tube 5. Therefore, inthe actual use, the water level of the water added in the liquid storagechamber 11 needs to be between the bottom of the oil storage tube andthe highest oil level.

In this embodiment, the bottom of the oil storage tube 5 may need to beset as close as possible to the lowest liquid level of the liquidstorage chamber 11, so that the water in the liquid storage chamber 11can support the essential oil 4 in the oil storage tube 5 in the processof gradual consumption, thereby obtaining the stable continuous oilsupply. If the bottom of the oil storage tube 5 is relatively high, oncethe water level is lower than the oil storage tube 5, the essential oil4 will all flow into the liquid 3, which causes a sudden increase of theessential oil concentration, and the gradual decrease of the essentialoil concentration subsequently, so that the stable concentration is notmaintained.

Embodiment 2

As shown in FIGS. 6 and 7, on the basis of the embodiment 1, the presentdisclosure provides an aroma diffuser. Different for the embodiment 1,in this embodiment, only one end of the oil storage tube 5 is sealed viathe first sealing member 61, and the other end is not sealed.

Correspondingly, since only the bottom end of the oil storage tube 5 issealed so that the air above the oil storage tube 5 may be in flowfluidic communication with the liquid storage chamber 11. Only the firstpuncture member 71 may need to be disposed on the fixing bracket 7, andthe second puncture member 81 may no longer need to be disposed.

For the bottom-sealed oil storage tube 5, since the bottom of the oilstorage tube 5 is sealed, the essential oil 4 may be added in the oilstorage tube 5 in advanced. The essential oil is supplied via followingsteps below:

a. adding the liquid 3 into the liquid storage chamber 11;

b. fixing the oil storage tube 5 containing the essential oil 4 on thefixing bracket 7, and letting the first puncture member 71 puncture thefirst sealing member 61.

The liquid level of the liquid in the liquid storage chamber 11 may bebetween the bottom of the oil storage tube 5 and a preset highest oillevel of the oil storage tube 5.

Compared with the way that the essential oil is directly dripped intothe water in the related art, the aroma diffuser provided in thisembodiment can continuously supply the oil to the liquid 3 in the liquidstorage chamber 11 in the above-mentioned method after the first sealingmember 61 is punctured by the first puncture member 71. As the aromadiffuser continues to work, the liquid 3 in the liquid storage chamber11 may be continuously atomized, the liquid level of the liquid 3 maycontinuously descend, so that at the bottom of the essential oil 4, thepressure exerted to the liquid 3 by the essential oil 4 may exceed thepressure exerted to the essential oil 4 by the liquid 3, and the liquidlevel of the essential oil 4 may also continuously descend. Theessential oil 4 at the bottom of the oil storage tube 5 may flow intothe liquid storage chamber 11 and mix with the liquid 3, therebyimplementing the continuous oil supply to the liquid 3 in the liquidstorage chamber 11 and the stable concentration of the essential oil 4in the liquid 3. Therefore, the essential oil concentration in theatomized vapor may be stable, which avoids the decrease of the essentialoil concentration with the increase of the use time. Since the oilstorage tube 5 with the sealed bottom is used, the essential oil 4 canbe stored in the oil storage tube 5 in advance. The oil storage tube 5may be directly fixed on the fixing bracket 7. The first sealing member61 may be punctured by the first puncture member, so that it is notnecessary to gradually add the essential oil into the oil storage tube5, which is very convenient to use.

Except that the second sealing member 62 and the second puncture member81 are not provided, and that the corresponding use method may bedifferent from that in the embodiment 1, the structure of the aromadiffusing apparatus in this embodiment may be basically the same as thatof the embodiment 1, and details are not described herein again.

Embodiment 3

As shown in FIG. 8, on the basis of the embodiment 1, the presentdisclosure provides an aroma diffuser. Different for the embodiment 1,in the aroma diffuser provided in this embodiment, the oil storage tube5 may be not a separately configured component, but is directlyconnected to the main body 1. In general, the top end and the bottom endof the oil storage tube 5 may be open and the top end of the oil storagetube 5 may be in fluidic communication with the liquid storage chamber11 while the bottom thereof may be in fluidic communication with theliquid 3, so before the aroma diffuser in this embodiment is used, theessential oil 4 can be added via the following steps:

a. adding water into the liquid storage chamber 11, where the waterlevel of the water in the liquid storage chamber 11 may be between thebottom of the oil storage tube 5 and a preset highest oil level of theoil storage tube 5;

b. adding the essential oil 4 into the oil storage tube 5.

Compared with the way that the essential oil is directly dripped intothe water in the related art, the aroma diffuser provided in thisembodiment may store a certain amount of essential oil in the oilstorage tube 5 in the above-mentioned method. As the aroma diffusercontinues to work, the liquid 3 such as water in the liquid storagechamber 11 may be continuously atomized, the liquid level of the liquid3 may continuously descend, so that at the bottom of the essential oil4, the pressure exerted to the liquid 3 by the essential oil 4 mayexceed the pressure exerted to the essential oil 4 by the liquid 3, andthe liquid level of the essential oil 4 may also continuously descend.The essential oil 4 at the bottom of the oil storage tube 5 may flowinto the liquid storage chamber 11 and mix with the liquid 3, therebyimplementing the continuous oil supply to the liquid 3 in the liquidstorage chamber 11 and the stable concentration of the essential oil 4in the liquid 3. Therefore, the essential oil concentration in theatomized vapor may be stable, which avoids the decrease of the essentialoil concentration with the increase of the use time.

In this embodiment, the oil storage tube 5 may be integrally formed inthe main body 1, or may be separately formed and fixed detachably to themain body 1 by means of sticking, clamping, or fixing via a fastener.

The structure of oil storage tube 5 may be various. Besides the designof the hollow cylinder shown in FIG. 1, the oil storage tube 5 mayfurther be designed as a funnel shown in FIG. 5. The top portion of theoil storage tube 5 may be connected to the top wall of the main body 1,and the bottom portion of the funnel-shaped oil storage tube 5 may beinserted into the bottom of the liquid storage chamber 11 via a pipe orthe like. All in all, the oil storage tube 5 may be designed as anyshape as long as the bottom of the oil storage tube 5 may be in fluidiccommunication with the liquid storage chamber 11. In this embodiment,the oil storage tube 5 may be disposed within the liquid storage chamber11 to make the aroma diffuser as a whole. In an embodiment, the oilstorage tube 5 may be disposed outside the liquid storage chamber 11.For example, the funnel-shaped oil storage tube 5 shown in FIG. 9 may bedisposed outside the liquid storage chamber 11. The bottom portion ofthe oil storage tube 5 may be inserted into the liquid storage chamber11, or the bottom of the oil storage tube 5 may be in fluidiccommunication with the liquid storage chamber 11 via a hole which isopened on the side of the main body 1.

In this embodiment, the main body 1 may be provided with a water inletand an essential oil inlet on the top portion of the liquid storagechamber 11, and the essential oil inlet may correspond to the oilstorage tube 5. The presence of the water inlet and the essential oilinlet enables the air above the liquid inside the liquid storage chamberto be in fluidic communication with the air above the essential oilinside the oil storage tube leading to the same air pressure at thesurface of the liquid as that at the surface of the essential oil. Theessential oil may be added into the oil storage tube 5 via the essentialoil inlet when the essential oil needs to be added. In addition, anessential oil storage tank may be preset on the main body 1correspondingly. The bottom portion of the essential oil storage tankmay be connected to the top portion of the oil storage tube 5 via apassage and a corresponding switch may be provided on the passage. Aftera certain amount of essential oil is pre-added into the essential oilstorage tank, the switch may be turned on, and the essential oil 4 maybe gradually added by controlling the degree of open of the switch, sothat the user does not need to continuously add the essential oil 4 intothe oil storage tube 5.

All in all, the aroma diffuser provided in the present application maystore a certain amount of essential oil in the oil storage tube 5. Whenthe aroma diffuser works normally, the bottom portion of the oil storagetube 5 may be in fluidic communication with the liquid storage chamber11, and the essential oil 4 can be kept in the oil storage tube 5 due tothe poor compatibility between the essential oil 4 and the liquid 3 andthe higher density of the liquid 3. Because the air applies a samepressure to surface of the liquid 3 as to the surface of the essentialoil 4, as the aroma diffuser continues to work, the liquid 3 in theliquid storage chamber 11 may be continuously atomized, the liquid levelmay continuously descend while at the bottom of the essential oil thepressure exerted to the liquid 3 by the essential oil 4 exceeds thepressure exerted to the essential oil 4 by the liquid 3, and the liquidlevel of the essential oil 4 may also continuously descends. Theessential oil 4 at the bottom of the oil storage tube 5 may flow intothe liquid storage chamber 11 and mix with the liquid 3, therebyimplementing the continuous oil supply to the liquid 3 in the liquidstorage chamber 11.

Compared with the way that the essential oil is directly dripped intothe water in the related art, the aroma diffuser in this embodiment cancontinuously and stably supply the oil to the liquid 3 in the liquidstorage chamber 11. During the use of the aroma diffuser, theconcentration of the essential oil 4 may kept stable, thereby keepingthe essential oil concentration in the atomized vapor stable, andavoiding the decrease of the essential oil concentration with theincrease of the use time. The above-mentioned content is the embodimentsof the present application, and the content of this specification is notto be construed as limiting the present disclosure.
